Why it works: Mustard and vinegar are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 14,067 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓

The flavor team
The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.
-

Shared aroma: isobutyraldehyde (malty, green).

Shared aroma: acetic acid (sour, vinegar).
Egg and vinegar barely smell alike, yet cooks put them together in 12,922 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Beaten raw eggs emulsify with the oil and vinegar, thickening the dressing into a creamy body.
- Sweet oil
- Provides fat that carries flavor and gives the dressing a smooth, rich texture.
- White vinegar
- Adds acidity that brightens the dressing and balances the richness of the oil and eggs.
- Mustard
- Helps stabilize the emulsion and adds a sharp, pungent flavor.
- Hard-boiled eggs
- Chopped eggs add bulk and a firm, mild texture to the salad.
The step that matters
Beat the eggs with oil, mustard, and vinegar. Raw egg proteins and mustard help hold oil and vinegar together as an emulsion. If the ingredients are added too fast or not beaten enough, the dressing can separate and look greasy. Mixing just before using keeps the emulsion from breaking.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar):
- Cucumberfits about as well
- Mustardthe original
- Capsicumfits about as well
- Shallotfits less well
Fit is the average pairing score against egg, vinegar. Candidates are from the same food group and used in at least 100 recipes.
